Bill Radke talks with music critics Jim DeRogatis and Greg Kot about the pivotal year of 1991 and how Nirvana's album "Nevermind" made Seattle the musical epicenter of the country. DeRogatis and Kot are co-hosts of Sound Opinions, which airs Sundays at 10 p.m. on KUOW.

Renate Senter clearly remembers the first care package she received, in 1946. She, her mother and her sister had fled Poland. In the aftermath of World War II, they'd ended up in a small town, in the British-controlled section of West Germany. "It was my first day of school and all the children got one," she says. "And I remember it was a small package — burgundy. And in white letters, it said 'CARE' on it."

Every year at the Kentucky Derby, crazy hat-wearing, mint julep-guzzling horse-gazers break into a passionate rendition of Kentucky's state song, "My Old Kentucky Home." As tradition goes, the University of Louisville Cardinal Marching Band accompanies the crowd as they croon a ballad that seems to be about people who miss their happy home. "The sun shines bright on my old Kentucky home/'Tis summer and the people are gay," begins one version.

But Frank X Walker, Kentucky's former poet laureate, suspects that most people are missing the point.

The Marine Corps is investigating whether some of the six men in the photo of the 1945 flag-raising in Iwo Jima, Japan, were misidentified after two amateur historians raised questions about the famous image and statue.

An ancient skeleton known as Kennewick Man moved a major step forward toward reburial Wednesday. The U.S. Army Corps of Engineers announced it has accepted DNA analysis that ties the remains found in the Tri-Cities to modern Native Americans.

On April 26, 1986, a routine test on reactor No. 4 at the Chernobyl nuclear power plant went horribly wrong. The reactor in Ukraine, in the old Soviet Union, went into meltdown. It became the world’s worst peacetime nuclear disaster.

A power surge during the test led to a rupture and a series of steam explosions. There was a massive leak of radiation, leading to fallout eventually landing all across Europe.

Dozens died in the struggle to contain the disaster. Hundreds of thousands of people were evacuated.

Treasury Secretary Jacob Lew announced on Wednesday that the countenance of abolitionist leader Harriet Tubman will grace a new $20 bill.

The decision caps a public campaign asking for a woman to be placed on American paper currency and months of deliberation by the Treasury to replace either Alexander Hamilton on the $10 bill or Andrew Jackson on the $20 bill.

Los Angeles is home to the largest Thai community outside of Thailand. This week, Thai-Americans are celebrating the traditional three-day water festival called Songkran to mark the new year. And many of them regularly shop at LA's landmark Bangkok Market, the first Thai food store in the U.S.

In the 1940s, an elite team of mathematicians and scientists started working on a project that would carry the U.S. into space, then on to the moon and Mars. They would eventually become NASA's Jet Propulsion Laboratory (or JPL), but here's what made them so unusual: Many of the people who charted the course to space exploration were women.

Nathalia Holt tells their story in her new book, Rise of the Rocket Girls: The Women Who Propelled Us, from Missiles to the Moon to Mars. Holt tells NPR's Ari Shapiro that the women worked as "computers."
